Good so far. Also, if you're lazy (like me :-), you can just put those RPM's in /home somewhere (if you have it NFS mounted on all machines), and therefore don't have to cpush. > cd /opt > > This command are to install a new version of LAM implementation: > > cexec rpm -i mpich_file_name.rpm > cexec rpm -i LAM_file_name.rpm > > I use the C3 to push the mpich rpm and LAM rpm in the nodes, and later I > execute the rpm command with c3. Also good. I would recommend installing the OSCAR-ized LAM RPM rather than the default LAM RPM (the main difference is where the RPM's are installed -- /usr or /opt/lam-<version>). If you don't have an OSCAR CVS checkout, you can get the OSCAR-ized LAM RPMs (6.5.9) from the web CVS stuff: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/oscar/oscar/packages/lam/RPMS/ > can the switcher see the changes?, that means the switcher will list the > new implementations of MPI? If you install the lam-oscar-module RPM, then yes -- switcher should see the new LAM version automatically. I don't have an OSCAR install to test this on manually, but I'm pretty sure that you should be able to have both versions of LAM and both switcher modules installed at the same time. Keep in mind that if you change the global switcher defaults, you'll need to cpush the central switcher config file to all nodes (switcher itself is not cluster-aware). See the OSCAR docs for the specific details. -- {+} Jeff Squyres {+} [EMAIL PROTECTED] {+} http://www.lam-mpi.org/ ------------------------------------------------------- This SF.net email is sponsored by: ValueWeb: Dedicated Hosting for just $79/mo with 500 GB of bandwidth!
